只需要在命令之前设置环境变量,简单来说比如原本程序是命令行运行python train.py 假定这里gpu总共有八块,通过nvidia-smi查看发现5,6,7是空闲的(从0开始编号) 则运行命令修改为:CUDA_VISIBLE_DEVICES=5,6,7 python train.py
在pychrm终端运行:CUDA_VISIBLE_DEVICES=0 python3.7 .\train.py --model model.pkl 报错了, 然后我又在cmd中运行,也同样报错 看了很多篇博客,不是说要在putty里面执行就是要在MobaXterm里面执行,但是这两个我电脑都没有,我就想,有没有简单一点的方法。 还真让我找到了,这篇博客说是因为环境的问题,我想到...
一个名为gpu_print.py的GPU程序如下所示: fromnumbaimportcudadefcpu_print():print("print by cpu.")@cuda.jitdefgpu_print():# GPU核函数print("print by gpu.")defmain():gpu_print[1,2]()cuda.synchronize()cpu_print()if__name__=="__main__":main() 使用CUDA_VISIBLE_DEVICES='0' python...

PyCUDA 是一个基于 NVIDIA CUDA 的 Python 库,用于在 GPU 上进行高性能计算。它提供了与 CUDA C 类似的接口,可以方便地利用 GPU 的并行计算能力进行科学计算、机器学习、深度学习等领域的计算任务。 安装pycuda 库 要开始使用 pycuda 库,首先需要安装它。
"forward":算子的方法名,假如算子的整个模块命名为sum_double,则在Python中通过sum_double.forward调用该算子 &two_sum_gpu:进行绑定的函数,这里根据自己实现的不同函数进行更改 "sum two arrays (CUDA)":算子注释,在Python端调用help(sum_double.forwar...
同样出现这个问题，明明有32G显存，但是给某个卡分配了30G显存，另三张卡分配不到1G，之后就OOM了：一...
